All Tuesday week afternoon she was hunting to match that chenille but at last she found what she wanted at Clery’s summer sales, the very it, slightly shopsoiled but you would never notice, seven fingers two and a penny
When asked to plan ahead and describe the most efficient route between two locations, we apparently visualise connections between highly salient streets, which leads us to formulate a relatively longer route, with fewer turns. This is known as graph-based way-finding.
But asked to actually walk between the same two points, we base our route more on direction, make more turns, take smaller streets, and navigate more efficiently, as ongoing feedback from the unfolding scene reminds us of short-cuts. This incremental approach is known as direction-based wayfinding.
The third mental strategy is brought to bear when we give directions to a stranger, with reference made to the simplest possible route, with the fewest turns and passing the most salient landmarks.
